WORKING TECHNIQUES
Cutting
The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you finish the cut.
Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen.
If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.
Turn the log and finish the cut from the opposite side.
The log is supported at one end. There is a high risk that it will split.
Start by cutting from below (about 1/3 of the way through).
Finish by cutting from above so that the two cuts meet.

Limbing
When limbing thick branches you should use the same approach as for cutting.
Cut difficult branches piece by piece.
Felling technique for tree tops
WARNING! It takes a lot of experience to fell
!a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level!
Safe distance
During tree maintenance work above ground level, the working area must always be secured and marked out with signs, tape or the like. The safe distance between the top of the tree that is to be felled and the nearest workplace must be at least 2 1/2 times the height of the tree. Make sure that no- one else is in this risk zone before or during felling.
Felling direction
The aim is to fell the tree in a position where you can limb and
Once you have decided which way you want the top of the tree to fall you must assess which way the top of the tree would fall naturally.
